The pathogenic mechanisms underlying Batten disease are unclear. Patients uniformly possess autoantibodies against glutamic acid decarboxylase (GAD) that are predominantly reactive with a region of GAD (amino acids 1 to 20) distinct from subjects with autoimmune type 1 diabetes or stiff-person syndrome. Batten patients did not possess autoantibodies against(More)
Patients and a mouse model of Batten disease, the juvenile form of neuronal ceroid lipofuscinosis (JNCL), raise autoantibodies against GAD65 and other brain-directed antigens. Here we investigate the adaptive component of the neuroimmune response. Cln3(-/-) mice have autoantibodies to GAD65 in their cerebrospinal fluid and elevated levels of brain bound(More)
Btn2p, a novel cytosolic coiled-coil protein in Saccharomyces cerevisiae, was previously shown to interact with and to be necessary for the correct localization of Rhb1p, a regulator of arginine uptake, and Yif1p, a Golgi protein. We now report the biochemical and physical interactions of Btn2p with Ist2p, a plasma membrane protein that is thought to have a(More)
The neuronal ceroid lipofuscinoses (NCLs) are the most common neurodegenerative disorders of childhood. We have examined mRNA levels of the CLN1, CLN2, and CLN3 genes, which are associated with the infantile, late infantile, and juvenile forms of NCL in 64 different human tissues, and have grouped the results into gastrointestinal tract, central nervous(More)
PURPOSE Juvenile neuronal ceroid lipofuscinosis (JNCL or Batten Disease) is one of the most common progressive neurodegenerative disorders of childhood, resulting from autosomal recessive inheritance of mutations in the CLN3 gene. Pathologically, Batten disease is characterized by lysosomal storage of autofluorescent material in all tissue types. Although(More)
Breast cancer is considered as an increasing major life-threatening concern among the malignancies encountered globally in females. Traditional therapy is far from satisfactory due to drug resistance and various side effects, thus a search for complementary/alternative medicines from natural sources with lesser side effects is being emphasized. Andrographis(More)
The neuronal ceroid lipofuscinoses (NCLs) are the most common neurodegenerative disorders of childhood. The CLN1, CLN2 and CLN3 genes are associated to the infantile, late infantile and juvenile forms of NCL, respectively. We have subcloned the cDNAs encoding CLN1, CLN2 and BTN1, the yeast homologue of human CLN3, into plasmid vectors to evaluate whether(More)
In this work, we report the antimicrobial efficacy of azetidinium functionalized polytetrahydrofurans in solution and their application in the preparation of non leaching, antimicrobial surfaces. The excellent antimicrobial efficacy of these water soluble polymers both in solution and on surfaces (>99.99%–100% bacterial growth inhibition) makes them(More)
